I've booked a IAH-DOH J flight with QR on points for a family member, and would like book a revenue ticket for transiting onwards to DXB.

IAH-DOH is scheduled to land at 5:05pm but is frequently delayed by up to 30min.

The last QR DOH-DXB flight of the day departs at 6:35pm. Would this be too risky of a connection, even if QR facilitates baggage transfer?

Might want to take a look here:

Were QR correct to offload us?

Ironically OP would have probably been okay on seperate tickets in this scenario.

Yep, I agree with Schwann on this one - with separate tickets the QR IT would have had no way to assess that a late arrival would mean they are under MCT and proactively cancel the onward sector.

Assuming the OP can do OLCI for the DXB flight they just need to get to Gate before it closes as Qatar will check any bags through if asked at the origin - as to see the check in supervisor if there is any query or pushback.

If the flight arrives on time into Doha 1h30 is fine, but 1h or less will start to get tight, especially as the OP will be taking the risk that if they fail to get to the gate Qatar do not need to offer the OP any protection or rebooking (but they might do as a customer service gesture if it was their own flight that delayed their arrival, there are some past examples, but don't depend on it)

Agreed, and in fact I�m doing the same in November albeit with a 4 hour connection on separate tickets. Was more focused on the other thread�s OP�s bus gate arrival time with a one hour connect time.

If the OP is checked through from IAH all the way to DXB, which is likely as they have bags, the system may in fact flag them as a connecting passenger. Check-in staff have the ability to manually locate an onward connection, which is how they print BPs even for other airlines. On the DOH side, if/when they look at the connections list, it's not immediately apparent that a passenger is connecting on separate tickets. Whether they choose to provide protection in the event of a misconnect is, of course, a different story.

I'll concede that I'm not 100% sure this is how it's done with QR, but it's common on other airlines that use Amadeus Altea.

TL;DR:
For self-connecting flights at Doha, is it possible to stay on the airside when the flights to and from Doha are operated by QR?

Long version:
I have the following itinerary booked separately: TPE-HKG-DOH-CDG

My self-connected layover is 2h55m at HKG and 3h50m at Doha.

TPE-HKG is operated by Cathay Pacific
HKG-DOH and DOH-CDG are operated by Qatar Airways

While I have confirmed with Cathay Pacific that they can through check my bag all the way to CDG, is this what I should be doing? Should I collect my checked bag at HKG and hand them to QR at HKG?

I believe I should be able to enter Qatar, I would like to stay on the airside at DOH if possible.Will I be able to get my DOH-CDG boarding pass when I am at HKG?

If CX can tag your bag all the way to CDG, then of course you'll stay airside at both connection points. Chances are you'll get your boarding passes all the way to CDG as well, but this isn't guaranteed. If you don't, just swing by the airside transfer desk at HKG/DOH to get them printed.

Staying airside is ideal, especially since you have less than 3 hours between separate tickets at HKG. Otherwise, you'd have to clear arrival formalities, collect your bag, and head upstairs to check in with QR. While HKG is quite efficient, keep in mind QR counters close 1 hour before departure, so you really wouldn't have much room for error.

Agree with all of the above, the only thing I would suggest in addition is at HKG would be to approach the gate staff dealing with the QR flight and ask them to check your bag has been correctly routed from CX to QR, show then your bag tag(s) you got in TPE. Try not to do this last-minute so there is some time if your bag for stuck for the baggage system to be kicked and correctly routed into the QR container in time for it to be loaded. If you have lounge access the lounge agents (at HKG this is going to be CX) can usually do this on QR's behalf, or staff on the transit desk if you want to get it done ahead of boarding.

Have a good flight.

Sorry if I have missed this but will QR still through check on seperate PNR’s?
Have CGK-DOH booked in QR J with Velocity points and then looking to get a revenue fare on QR DOH-KWI with only 90 minutes connection. Will QR check my bags through to KWI when I check in at CGK?

ISO far, I have not seen any post where QR would not interline QR to QR on separate tickets.

You might also look at:
QR Interlining (Baggage)

For some reason i could not book AKL-DOH-CDG on a single PNR with BA (QR J class) and had to book the flights separately (with a large layover to hopefully avoid missing the flight)
I'm just double checking there is any unexpected issues transiting on separate tickets on an NZ passport. Ill ask QR to interline my baggage, but worst case i have enough time to go fetch them in Doha.
AKL-DOH � QR921 - 8 hour layover - DOH-CDG � QR039

The issue isn't QR. Issue is the agents QR use at AKL will likely insist can't be done. I've had this issue at AKL frequently. More so when NZ is the ground agent, but still have had issues with all of themvat various points.

Are you saying NZ ground agents wont interline QR > QR on separate PNRs?
Sadly the QR official policy seems to have disappeared from online, that said flew QR last month from BNE to LHR and then onward to Faro on BA and it wasnt an issue having bags interlined to separate PNR , shame the NZ staff arent playing nicely! Never collected bags at DOHA to be fair.. guess with an 8 hour layover it wont be an issue if NZ agents dont interline.

I'd say also just make sure you have a passport from a Visa Waiver country (which seems to be better than half of the world now). Especially if they refuse to through check your bag they could also deny boarding if you aren't visa waiver eligible or have an e-visa.
